Nanosensors for Chemical and Biological Applications: Sensing with Nanotubes, Nanowires and Nanoparticles

The unique electronic, optical, magnetic, as well as chemical properties of nano-scale materials are very attractive for realizing fast-responding sensors with good sensitivity and selectivity for the detection of chemical species and biological agents. Part one reviews the range electrochemical nanosensors, including the use of carbon nanotubes, glucose nanosensors, chemiresistor sensors using metal oxides and nanoparticles. Part two discusses spectrographic nanosensors such as surface-enhanced Raman scattering (SERS) nanoparticle sensors, the use of coated gold nanoparticles and semiconductor quantum dots.
